Paul, do we really want to keep specifying replacement files'
locations on a per file basis?  How about speicifying a directory,
AC_CONFIG_LIBOBJ_DIR or so?  I'm worried, because each time we add an
argument, we make it less possible to have

AC_CHECK_FUNCS(fnamtch)

AC_REPLACE_FUNCS(fnamtch)

do the right thing automatically.  This is still something I plan to
implement some day (as, the user still needs to be an Autoconf expert
to write the right configure.ac).
